Just for fun is correct about DCS and LIRF. If not a manual loading instruction has to be prepared. The LIRF must be signed by the ramp team leader before the aircraft is pushed back. The Dispatcher must ensure that any amendments to the Loading are reflected in the Loadsheet - ie if you add on a rush bag an extra 13kgs must be added to the load sheet - otherwise its a missload for which ultimately the Dispatcher/Ramp Team leader can be dissmissed.
